BUFFER.

SPECIFICATION forming part of Letters Patent No. 425,632, dated April 15, 1890.

Application filed Tune 29, 1889. Serial No. 315,992. (No model.)

To aZZ whom, it may concern:

Be it known that 1, ANDREW W. ROGERS, of Beverly, in the county of Essex and State of Massachusetts, have invented a new and useful Improvement in Buffers; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to the abrading-covers for buffer-feet. It is designed principally for that class of buffers used in finishing the soles of boots and shoes. These abradingcovers wear rapidly, and it is very desirable that they should be cheaply made and that they should be capable of easy attachment to the foot of the buffer and should be easily removable therefrom. At the same time it is also desirable that they should be firmly held against turning upon the foot when the foot is rotated in use, that the edge of the buffer should be clear of abrading material in order that it'may work up against the breast of the heel without injury to the surface, and that the face of the abrading-covering should be a continuous surface. These conditions have been met more or less fully by various forms of devices combined with an abrading-disk, not necessary herein to be enumerated. The invention herein described is designed to accomplish all the objects and fulfill all the conditions above referred to in a complete manner. j

The invention consists, principally, in combining with anabrading-disk a central but ton of wood or some equivalent material of sufficient strength and rigidity for the purpose, this button-disk being attached to the inner face of the cover and serving at the same time to strengthen the abrading disk or cover.

Further, the invention consists in utilizing the re-enforcing button as a means of connection with the foot of the buffer.

The invention consists, also, of projections set at various points on the interior surface of the abrading-disk and between its margin and the margin of the button above referred to, said projections being fixed to said face and adapted to enter the foot of the buffer and to hold it against lateral displacement under the strain caused by the turning of the foot when the abrading-snrface is brought into contact with the sole of the boot orshoe.

The invention also consists in the special construction of the button and the connections for holding it to the foot.

The invention is shown *in the accompanying drawings, in which Figure 1 is a sectional view of the foot, covering, and fastening devices. Fig. 2 is a sectional view of a modification.

In the drawings, A represents the abrading-disk. This is commonly made consisting of a disk of sand-paper or emery-cloth, although other materials are known as equivalents. These disks are thin, but have some stiffness, suited to the work for which they are intended. They are cut out of sheets of material, and this mode of formation leaves the edge Without abrading material. Ordinarily these disks are made in eoncavo convex form, the convex surface being the abrading-surface. On the inner face of this disk and centrally located is a button 13. This I make ordinarily of wood, which forms a very cheap and efficient material for the purpose. The button is made 011 its lower face to fit the disk A of sand-paper, and the upper surface is also convex-formed with beveled edges, so I that it is thicker in the center and thinner toward the margin. A central hole ais formed directly through the button to receive the end of the stem 0 for holding the cover to the foot. The button is firmly glued to the inner face of the disk, which is then in condition for attachment to the foot of the buffer. The buffer-foot isformed on its lower face with a hollow adapted to receive the button and fit snugly both to the button and to the abrading-disk.

For cheapness of manufacture the hole in the center of the button is made round and fitted accurately to the lower end I) of the stem O, this lower end. projecting sufliciently far to pass into the button.

In order to hold the cover against turning when the foot is rotated, knife-edges} are inserted longitudinally in the projecting part 0. of the end of the stem. Instead of this, the hole may be made angular to accomplish the same results. In whatever form the stems should fit snugly in the hole, so as to cause the covering to adhere to the buffer-foot by the frictional contactof the parts. This is sufficient to hold the parts together and prevent the cover from dropping olf in handling, and the glue holds the central part of the abradiug-disk firmly to the button.

For increased security against tendency of the disk to turn on the button,especially if there be a wide margin left outside of the margin of the button, I provide projectionssuch, for example, as those shown at cl. These I prefer to make of wood, and they may be.

turned out of any suitable wood with fiat bases and tapering or cone-shaped pointed tops. The bases are glued to the inner face of the covering at regular intervals circumferentially on the margin notoccupied by the button. The points easily penetrate the felt of the foot and hold the margin against tendency to turn or tear in the rotation of the buffer when applied to the sole of the boot or shoe. While I have described these projections as made of Wood, preferably, they may be of other material. I have also described the button as being of one piece of wood. It may also be made of pulp, fiber, or any other suitable material by stamping or pressing.

In order to extend the margin of the button-piece, it may be made in two parts, as shown in Fig. 2, by making the button itself smaller and re-enforcing it underneath by a disk of veneer, as E, the button itself being represented by B.

The projections may be more or less in number, according to the strength of the material and the size of the button, and, for example, may be used on opposite sides of three or four set at equal distance.

I have shown the button as provided with a central hole to receive the stem of the spindle. It is obvious that the stem may be on the button and the hole in the spindle end with substantially the same effect.

I claim as my invention- 1. As an improved article of manufacture,

an abrading-covering having a re-enforcing button fixed directly to the inner face thereof at its center, substantially as described.

2. In combination with the yielding foot of a buffer, an abrading-cover and a re-enforcing button fixed directly to the inner face of the cover at its center, thesaid button forminga means of connection with the stem of the buffer-foot, substantially as described.

3. In combination with an abrading-covering having a button fixed to its central i11- ner face, a felt foot, and projections set at intervals directly to the inner face of the covering adapted to enter the felt foot and hold the covering against turning, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
